What are the upstream raw materials for ethylene? What do the downstream products contain?

Based on my observations, Ethylene is an crucial raw material to chemical production, with a wide range of upstream and downstream related items. The following are some of the upstream and downstream associated items of ethylene:



1. Upstream items:(1) Petroleum: Ethylene is mainly derived from petroleum cracking, so petroleum is the main upstream feedstock to ethylene. In fact(2) Natural gaseous: Natural gaseous is able to also be applied to create ethylene, however it's relatively rarely applied. And(3) Coal: Coal is able to be converted into synthesis gaseous through gasification, liquefaction and other processes, and then further converted into ethylene. But

2. Downstream items:(1) Polyethylene(PE): Ethylene is able to be polymerized to create polyethylene, which is a broadly applied plastic material to the production of various daily necessities, packaging materials, pipes, etc.(2) Ethylene propylene rubber(EPDM): ethylene is able to be copolymerized with propylene to create ethylene propylene rubber, which is applied to create rubber items with oil resistance, acid resistance, oxidation resistance and other performance standards.(3) Ethanol: Ethylene is able to generate ethanol through hydration interaction, which is an crucial organic solvent-based products and chemical raw material.(4) Acetaldehyde: Ethylene is able to generate acetaldehyde through oxidation interaction, which is an crucial organic chemical raw material to the production of plastics, fibers, medicines, etc.(5) Acetic acid: Acetaldehyde is able to be further oxidized to form acetic acid, which is an crucial organic acid applied in the production of cellulose acetate, acetate, etc. Additionally The above only lists some upstream and downstream related items of ethylene. In fact, ethylene is broadly applied in chemical production, and there are many other upstream and downstream related items.
